Serial No. 194,364.

designates a rectangular sheet from which my envelop is constructed. Thesheet 5 divided off into sections 7, 8, 9 yand 10. The sections 7 and 8are divided by the line 11, the sections 8 and 9 are divided by the line12 and the sections 9 and 10 are divided by the line 13. At the point ofconnection lof the section 8 with the section 9 there is provided atongue 111- which is defined by slitting the section 8 yas at 15.

The section 7 is provided With the side flaps 16 and sealing tongue 17and the side iiaps and tongue provided on one face With a suitableadhesive 18 and 18. The section 9 .is provided with side liaps 19 whichare provided on one face with a suitable adhesive 19. The section 10 isprovided with side flaps 20 and a sealing tongue 21 which are providedon one faceV with a suitable adhesive 22. The adhesive on the flaps .20and the sealing tongue 21 is on the reverse side to the adhesive whichisron the side flaps 16 and 19 and the sealing tongue 17 of the sec'-tions 7 and 9 respectively.

When folding the preferred form of the envelop to provide a plurality ofpockets, it is only necessary after the initial fold to fold thesections 9 and 10 back upon the sections 7 and 8, folding the blank onthe line 12. Thusvthe line 13 is in alinement with the line 11 and theenvelop is then folded on the lines 11 and 13, respectively, folding thesection 10, thereby illustrating the construction shown in Fig. 5. Theside fla-ps 16 are then sealed to the side flaps 19 which are in turnsealed to the side Haps 20 and the side flaps 20 are secured against theouter face of the section 8, thereby providing a plurality ofindependent pockets which maybe effectively sealed by the tongues 14, 17and 21.

It is to be understood that these pockets may be independently sealed ormay be all sealed at one time, thus completely closing the envelop andpermitting it to be transported through the mails Without liability ofits contents being lost.

Fig. 4; illustrates the initial folding operation of the blank and Fig.5 illustrates the blank when in fully closedposition prior to sealingthe side flaps and'tongue.

W'hat is claimed is An envelop comprising a blank divided into fourintegral sections and having struck up there from a tongue adjacent theedge of the third section und forming a slot in the second section, sideflaps formed on the irst` third and fourth sections, sealing tonguesformed on the edges of the iirst and fourth sections, said tongues andflaps having udhesive thereon, said third and fourth seotions beingfolded back on the fir-stand ond sections and then the second and thirdsections folded on the first and fourth seetions to form @plurality ofpockets and disposing the sealing tongues and the first named tongue ineloserelation to euoh other for closing the pocket-s, said flaps beingsealed together and to one lce of the seeond section, said slot forminga mouth to one 15 of the pockets.
